I'm not sure which of the following fixed the looping problem, but it is fixed.
We purchased TurboTax from Costco and called the number on the back of the disc ([phone number removed]). The help desk sent me a download via email to install updates (as opposed to the normal updates that happen every time I log on). First time I tried to get past the stuck screen after the download, I continued to get the whirling circle and "Not responding". The help desk put me on hold while they were making arrangements to get me a new version of TurboTax to download. I walked away from computer for at least 5 to 10 minutes and when I returned TurboTax was responding and never locked up again. I did not download a new version nor did I uninstall and reinstall TurboTax; though uninstall/reinstall was also suggested. I do not know if I just needed to leave it in the "Not responding" error run for 10 minutes or there was something critical in the download PLUS the 10 minute wait that got me by this hurdle. FYI, it is not my system, my PC far exceeds the requirements set by TurboTax as minimum requirements.
